The term aggregate generally refers to all types of sand, gravel and crushed stone, which are used in various construction applications and are the product of mines or quarries. Sand and gravel are used to build roads, sidewalks, buildings, factories, parking lots, walls, roofs, parks, sports fields, landscaping and trails, and many other applications. Industrial sand could be used in the glass manufacturing process, gravel for roofing paper, and additives for paint and stucco. Sand and gravel are naturally occurring, usually in pits, while crushed stone is the product of blasting, crushing and processing of rocks, usually found in quarries.
Raw materials go through many steps before they are sold to end-users. A pile of aggregate has a distribution of particle sizes, ranging from small sands to pebbles 6 inches and higher. The first operation is usually a jaw crusher; two plates are pushed together on a rotating basis to crush large rocks in the deposits. The conveyor belt sends the product to be screened and then resend to the cone crusher for larger particles.
Screening and sorting separate particles of similar size into piles. This is achieved by using industrial or vibrating screens or cloths.
The remaining larger particles are sent back to the cone crusher, breaks down the size furthermore. The products are then send the back to screening. For any larger sizes left on the top of the screen, this recirculation occurs repeatedly. In a rock quarry, recirculation through the cone crusher is even more common.
Depending on the type of product, washing cycles may also be included. The washed or removed gravel will remove any fine powder (dust, clay, fine particles).
As one of the specialized aggregate screen manufacturers, Anpeng has high-quality gravel screen for sale. Clogging ia a common problem in the screening of aggregates especially in gravel and crushed stone screening, because of the anomalous shape and relatively large particle size. In response to the problems of polyurethane vibrating screens clogging and pegging in applications, Anpeng has developed the self-cleaning screen series, that's uniquely designed to effectively solve these problems, and greatly increase efficiency.
In the selection of aggregate screens, the nature, and characteristics of materials, should be taken into consideration, tailored and suitable solutions offered by our aggregate screen manufacturers could always improve efficiency and reduce your engineering costs.
In the selection of aggregate screens, production conditions and the properties and characteristics of rocks should be fully considered in order to select suitable aggregate screens, in order to improve efficiency and reduce engineering costs.
